J. Cent. South Univ. (2021) 28: 747-759 DOI: https://doi.org/10.1007/s11771-021-4642-9 Moving target detection based on improved ghost suppression and adaptive visual background extraction LIU Ling... background extraction algorithm (ViBe) uses the first frame image to initialize the background model, which can easily introduce the "ghost". Because ViBe uses the fixed segmentation threshold......

solid solubility Cmax of alloys is one of the basic issues of the theoretical research on phase formation. It is significant to understand the phase formation theory and improve the ability to predict... in vanadium whose maximum solid solution limits are not sure from the phase diagram. Function Zf can explain the rules of D-G theo rem, which is proved to be the special examples of Cmax equation......

(GdEr) phase was changed into fragmentized island morphology and the volume faction of the phase decreased. After solution solid treatment at 460 °C for 6 h, the Mg5(GdEr) phase was already completely.... It was suggested that the microstructure evolution of the alloy during the solid solution treatment was concluded as follows: Mg5(GdEr) eutectic phase→Gd/Er atom diffusing into matrix→spheroidic Mg5(GdEr......
